iMPROVED WASHING-MACHINE. i

Ispcclicutinn forming part of Letters Patent No. 45.311, dated December6, lt;

showing'l the rotating rubber in a positionforl aetingupon the articlesin the machine. Fig. 3 is a top view with the cover removed. Similarletters ot' reference indicate corre; sponding parts in the threefigures.

The object of my invention is to so construct a rotating slattedrubberthat-when it is com -Y bined with an inclined wash-board it willop crate intermittently upon the articles placed in the tub, andnot'only squeeze and rub them, but also allow them to open and absorbwater after .each squeezing and rubbing operation,

' as will bev hereinafter described.

To enable others skilled in the art. to make land use my invention, Iwill describe its con-1 struction and operation.

In the accompanying drawings, A represents the wash-box, which is madewith vertical sides and inclined ends; and B represents a rotatingrubber, which is supported by a horizontal transverse crank-shaft, a,passing through its heads b b and resting in hearings in the sides ofthe wash-box. This rubber is chiefly composed of slats or strips c c',having roughened or corrugated surfaces, which latter are also slightlycurved, as shown in Figs. l. and 2 The heads of the rubber, to whichthese corrugated and convex-surface slats are secured are polygonal, andthe slats c c are arranged in pairs, so as to leave a space beasindicated at d. These three points d d d of the rubber are considerablynearer the shaft a than the surfaces of the slats c, and the slats cgradually approach said shaft as they diverge from the planesoil theslats c. The three angles e e e are the farthest from the axis otl therubber B, and the angles c c' e are-nearest said axis. By this form ot'rubber I obtain an intermitting rub bing and pressing action ot theslats c c upon inafter shown.

The slatsy may be made up ot' narrow bars, orthey may be made ot' widestrips having perforations through them.

Those which are lettered c, and which give the greatest pressnre to thearticles in the tub, may be pertbrated, while those lettered c', whichperform the rubbing, perforated.

may be made solider left im- ()n the bottom ot' the wash-tub A, and arranged a little on one side ot' the rubber B, are

Aa number of rounded bars, f f, which gradually increase in size, andwhich extend transverscly across junction the bottom of the tub. Inconwith. these bars f, l employT an iu cliued wash-board, C, the lowerend ot' which `rests'upon the bottom ot' the tub and is very curved, soas surface,

The upper ends ot' this wash-board C have pinsg' projecting from themand notchesfformed in segmental side supports,

en terin g D D, which latter form supportst'or said washboard wh 'n itis arranged in'diterent planes.

In Fig. 1 I have represented the rubber B in a position tor receivingarticles under it to bewashed, and in Fig. 2 this rubber is representedin a position 'for acting upon the artielcs. l t will be seen that inthe former instance oue of the spaces d brought over the Fixed rubbingslats or ot' the rubber is bars j' ou the bottom of `the tub, and as theradius of the rubber B is lvery short at this point d,

a very large space will be left between it and the bottom of the tub;

sutticient to allow the articles to be washed to work themselvesdirectly beneath the rubber, in a position to be acted upon by thesucceeding pair o't' rubbing and pressing slats c c'.

c c' are represented as acting upon the articles,

which are partially held au 'place by means ot' the fixed slats orbarsj'. `As tl'te extreme outer edge of the slat c is moved toward thearticles.

they receive a considerable pressure from it, and are at the same timerolled over to present new surfaces to be acted upon by the succeedingrubbing and squeezing slats c c'; but bet'cre this second operationtakes place another space d is brought over the articles,

and they are allowed to absorb water and soap the articles placed in thetub, as will be here "slightly inclined, while the upper surt'ltee'is"to present a concave rubbing.. as clearly shown iu Figs. l and 2.'

In Fig. 2 these slats again. By the peculiar eccentriearrangement of'the rubbing andsqueezingslats upon the heads of the rotating rubber itwill be seen that the operation of Veach pair of these slats Y isgraduallsT augmented, and that the greatestpressure occurs at the pointse e e, while the least pressure occurs at the points e; hence 111earticles are rubbed and pressed.

The object of providing for adjusting the upper end of the Wash-board Gis to adapt they machine for washing either very`large or very and tofacilitato the removal small articles, of artielesfroln the tub afterthey have been washed.

y ters Patent, is-` Having thus ldescribml my invention, what I elaim asnew, and-desire to secure by Let- 1. The rubber and squeezer-eonstructcd with openings dd between the rubbing` and squeezing'devices, substantially as and for the purposes set fort 2. Thecombination of a polygonal rotating rubber, B, with a wasli-boar(l, C,and slatted bed f, substantially as described.
